Extending the idea of a
I am not discussing use cases, at least in this initial message, because most of these units are intended for future devices but are already applicable to styles build with existing CSS modules.
Anthropometric length units
All anthropometric length units are defined as the diameter of the smallest circle that contains a touch print of a particular human body part. The default or fallback values provided are rough estimates, open to discussion. They are not (yet) based upon empiricial data, but approximate physical units that do not depend on the anchor unit (usually
Anthropometric time units
I’m proposing two psychological temporal units and two physiological temporal units.
In psychology, instant and moment have conventional absolute definitions. They are complicated to measure for an individual user in the current situation, but different values may apply for some age groups or users of certain assistive technology.
Recent advances in sensor technology have brought devices to the consumer market that are able to measure a user’s physiology, e.g. their pulse rate or heart beat (especially in “smart watches”) or the rate and duration of their eye blinks (expected for head gear like AR/VR goggles).
I think you really should. Without use cases, I don't think this has any chance of making any progress.
For the other units you are proposing, I do not know what they are supposed to be used for, so I have no basis to judge whether they're doing any good.
One reason I proposed these units, obviously, is to cover the use cases brought forward before by other contributors to www-style for “real” or “true” physical units that are not anchored to
As for use cases, they mostly follow from the ones raised for
As for the temporal units,
